		//1.实现写死json字符串，解析展现到页面上
		var jsonstr = '[{"p":"1799.00","op":"17999.00","cbf":"0","id":"J_100010378153","m":"100000.00"}]';
		
		//2. 获取价格和编号
		var obj = JSON.parse(jsonstr);	//把字符串转换js对象
		
		var price = obj[0].p; //获取到数组第一条记录，访问p属性
		var id = obj[0].id;
		
		console.log(price);
		console.log(id);
		
		//3. 把内容写到页面，进行展现
		$("#id").text(id);		//span标签属性写法
		$("#id").css("color", "blue"); //渲染render
		
		$("#price").text(price).css("color","red");		//链式编程
